CC-1 — Zea mays

Summary

ZM00001EB145520, designated CC-1, is a maize gene on chromosome 3 encoding a cytochrome c family protein with electron transfer activity and heme binding. The product localizes to the mitochondrial envelope lumen and is associated with mitochondrial electron transport from ubiquinol to cytochrome c and from cytochrome c to oxygen, as well as complex III assembly, oxidative phosphorylation, and release of cytochrome c from mitochondria. The gene has been linked to anti-apoptosis, mitochondrial gene expression, and response to stimulus. In terms of agronomic traits, CC-1 is associated with grain yield, heterosis, germination rate, chlorophyll content, protein content, carbon content, net photosynthetic rate, quantum yield, respiration rate, and cold tolerance. Studies of related genes in other species support the family's role in mitochondrial respiration.
